Pressure Sensor Available in High Pressure Ratings

Oct. 31, 2006
American Sensor Technologies (AST), a New Jersey-based manufacturer of state of the art MEMS-based pressure sensing products, introduces the new AST47HP Series of Pressure Sensors. This new line addresses the growing need for pressure sensors with higher pressure ratings. Available in pressure ratings up to 60,000 PSIG (4,000 Bar), the AST47HP Pressure Sensors are ideal for operation in diesel fuel rails, high-pressure wells, hydraulics, injection molding equipment, water jets, down hole instrumentation and more. “With an increasing emphasis on vehicle efficiency, diesel fuel rail systems are being redesigned to run at higher pressures,” states Karmjit Sidhu, AST’s Vice President of Business Development. “AST is able to meet the new requirements of engine manufacturers by supplying AST47HP Pressure Sensors with pressure ratings up to 60,000 PSIG.” The AST47HP is also popular among water jetting applications used in food processing, concrete and tile cutting, and metal fabrication. AST47HP sensors incorporate a one-piece stainless steel sensing element, which is free of silicone oil, welds or O-rings. The absence of these characteristics eliminates the chance of contamination from outside media, critical in food processing applications. With AST’s Krystal Bond Technology, the sensing element offers a thick diaphragm that eliminates long-term drift, which can be common in high presure and high cycle applications. A stainless steel housing is welded to the sensing element for optimum protection of the sensor's electronics. Units are rated for over 100 million pressure cycles and have 100V/m of EMI/RFI to protect against electrical noise. • Accuracy1- < ± 0.5% BFSL • Stability (1 Year)- ±0.25%FS, typ • Pressure Cycles- >100 Million • Temperature • Operating- -40 to 85°C (-40 to 185°F) • Storage- -40 to 125°C (-40 to 250°F) • Thermal Limits • Compensated Range- 0 to 55°C (30 to 130°F) • Temp.
